This paper investigates feasibility and performance of a novel proposal of using an automatically extending active bumper system to absorb impact energy in vehicle frontal collisions. It is proposed to use a 1.5 m extending bumper supported by two hydraulic cylinders fixed to the longitudinal columns of the vehicle. A specially adapted fast response hydraulic flow control valve with a learning digital computer control is proposed. Simulation investigations revealed a maximum level of 7g deceleration could be achieved in a 30 mph collision.
